To all whom it may coi'bcern:

Be it known that l, Ennemis l?. Pmie'ror-i, a citizen of the United Humm, resid-iig at La Grange, in the countyr of Cook and .5ta e of Illinois, have invented Le* :iin new und. useful Improvii-niente in Vaporizing and Mixing Devicee, of which the. following a specification.

My invention relatee` to a` vaporizii mixing device intended particularly to he used on an internal rmnhustion engine for vaporizing the hydrocarbon. element and mixing it with air; and the invention has for its object to provide a device of this character which can` he used either as an auxiliary to the ordinary carburetor., where gasolene is used, for making the mixture from the earbureter more intimate and more thoroughly 'vaporizing the gesolene before the mixture goes to the cylinder; which can be used in place of the carhureter to ac coinplish the ordinary functions of the cai bui-eter; or which, when gas used a fuel, will thoroughly mix the with air hefore it is exploV ed. f

The invention has f or further ohject eur-fh new and improved constructions in vapori?,- iug andfniixing devices as will he described in the following specification and particu larly set forth in the claims appended thereto.

One embodiment olf niyinrention' ie. shown in the aeeornpauyiug` drawings. wherein-- Figure 1 is a longitudinal cef-.tion through the device. i taken on line Q-l of Fir l, looking in the direction of the arrowV` ltig. 3 is a crossA Sectional View taken on liuc ot' Fig. l. looking in the direction of the arrovs: and Fig. 4: isa crosuecction on line. will of Fig. 1, looking' in the .lirection oi the arrows,

I hare shown a preferred way of no conlphshmg this1 which o; to arrange the `ditcrent sets of tubes or conduits so that the,

entering und outgoing seth` of each chaiuher overlap. For example, in the purrorations of partition 18 are Seli tubes 22. which extend l substantially to partition lll, their discharge ends heine eut oli' on the diagonal, so that the tahoe diS-Iiliarge toward the center ot thtl casi. The next set of tutti@ 2i-3 extend from poilus adiaeent partition irl through partition t9 to ponne adjacent partition 0, the

inlets 2l ot' these conduits facing toward the circumference of the canino, their dirharge openings. being opposite v disposed. An other set of tubes 26 provided haring inlets 2l' adjacent partition it! and facing the circumference of the ramingq extending through partition *2U and terminating at partition 2l, and with dichargo openings 2b' facing inwardly. To complete the htruclorc shown, another Se of tuhee 29 is provided haring outwardly kicing` iulcu und set in the perforations in partition "il, When the inlet and outlet are in the renter ol the cae-ing. l preferably forni the tuhe or conduite of graduated diameteru` the outer tubes beingl largerto con'ipensate for the decrezmed pren` sure around the wall ot the derive. l prefcrahly also construct-the device with lneanh 'lor adluitt ing air to the interim ol the raSing in. regulutahle quantities.
